Question

A heat engine has a hot reservoir of 490°C and a cold reservoir of 210°C. What is the efficiency of the engine?

A. 62.3% B. 52.6% C. 57.1% D. 48.2%

Answer 1

I can give you the maximum possible efficiency of the engine.

Answer 2

What is it lol :)

Answer 3

Considering a carnot's cycle,
\[\eta = 1- T _{2}/T _{1} \]
where n - efficiency
T(2)- temperature of cold reservoir
T(1)- of hot reservoir

Answer 4

If you put values, you get close to C.

Answer 5

yes lol thats what i got :) thank you do you think you can help me with my physics test ?

Answer 6

Yeah, I will try my best.

Answer 7

okay hold up ill show you the rest of the questions
